1 Claim.

This invention relates to improved pilot means for accelerating the flow of gaseous fuel through a conduit to a burner.

An object of my invention is to provide improved means mounted in a gas supply pipe which increases the velocity of gaseous fuel delivered to a burner and at the same time effects the mixture of suitable quantities of air with the fuel to insure proper and efficient combustion.

Another object of my invention is to'provide a nozzle for use in directing quantities of gaseous fuel through a conduit leading to a burner, having adjustable means at its end for increasing or diminishing the velocity of the fuel discharged therefrom.

Other objects more or less apparent will present themselves or will be specifically pointed out in the description to follow.

In the accompanying drawing:

Fig. 1 is a top plan view, partly in section,'of

apparatus embodying my invention;

Fig. 2 is a longitudinal sectional view taken through the axis of my improved nozzle;

Fig. 3 is a front view of a bracket employed in maintaining the nozzle in a proper operating position at the end of a conduit leading to a gas burner; and

Fig. 4 is a side view, partly in section, of a nozzle embodying my invention, showing the adjustable means at the discharge end forincreasing or decreasing the velocity of the gaseous fuel expelled therefrom.

Referring to the drawing, the numeral 1 designates a gas burner having a fuel supply conduit 2 connected thereto. The conduit is provided with an enlarged open end 3, upon which is clamped the spaced legs of a bracket 4. The bracket is provided with a central opening 5 within which is mounted and suitably supported, a nozzle 6. Thenozzle is tapped to provide means for connecting it to a pipe 7 leading from a source of gas supply. The nozzle 6 is provided with a tapered intermediary part 8 which terminates in a narrow tubular end part 9. The opening through the tubular end part 9 is considerably restricted in comparison to the opening in the main body of the nozzle, thereby affording means for increasing the velocity of the gaseous fuel discharged into the conduit 2.

vide adjustable means for increasing still further the velocity of the gas discharged from the nozzle, I have provided a series of tubular telescopically arranged members 10 and 11 on the end part 9 The tubular member 10 is adapted 55 to be frictionally but removably maintained in the end part 9, while the still smaller tubular member 11 is similarly maintained inside the preceding tubular member 10. By providing means such as the removable telescopic tubular members, the velocity of the gaseous fuel discharged from the nozzle may be varied to meet different conditions, thereby enabling suitable adjustments to be made to produce better and more efficient combustion. The discharge end of the nozzle extends far enough into the conduit 2 to prevent the curved enlarged end of the latter from interfering with the force and movement of of the nozzle.

the gaseous fuel toward the burner.

Suitable quantities of air to mix with the gas discharged by the nozzle are drawn through the open end of the conduit between the legs of bracket 4.

Having described my invention, what I claim in combination, a burner, a conduit connected to the burner having an open end, a bracket secured-on the open end of the conduit having air openings therein, a nozzle supported by the bracket and extending into the conduit, the said the nozzle.
